Sintered Brake Pads 3

[metalman8357]

Does anyone know what type of material is used to make sintered brake pads? I have designed a custom cone clutch for a recreation project and I would like to have custom rings made out of brake material. I was just wondering what this material is, and if I can contact a place to have these made custom. Also, I'm trying to do some calculations on wear rate between brake material and steel, but I'm not sure where to start (just want to get a rough estimate of product lifetime). Any ideas?

You can find lots of info from SAE Technical Papers. Look for a University library that has these if you cannot obtain them directly. The link below is for some recent papers, but search the entire database for others:

You might want to check with companies like Hawk Performance and Performance Friction. They make low volume, high performance friction materials, so they may be able to supply you with what you need.

One common material for disc brake pads is sintered copper. The powder used is actually a combination of copper and other materials. The copper particles help with thermal management.

Hope that helps.

Here is a pretty good summary of friction materials. It is a little dated but has the basics.

From a recent project of investigating a semi-metallic brake pad from an ATV, I found the main material to be calcium silicate with mostly brass and steel fibers scattered throughout. The CaSi has decent wear resistance as a ceramic and the the metal fibers help prevent heat fade, as tbuelna mentioned.
